Looks like this afternoon will be relatively "dry" as the showers west of the area move north. NAM has only about .05" through tonight with heavy stuff coming in after midnight.

Yup, the SPC WRF doesn't have any more legit convection coming in until 34-36 hours (last nights 00z run)

Seriously, may try to hit the links late, would like it a little warmer.

If it makes it, temps should pop 10-15 degrees. Lets hope.

Wanna go fishing after work before the atrocious weather keeps boat at dock, for a few days.

How much rain does the new Euro show?

2-3" total or most of the area, underdone if you ask me and the euro is probly the worst model to use for qpf when the event is near.

the slow moving nature of the rain/storms and training nature due to the cutoff will get alot areas over 4 or 5" imo

can you refer to models by 12z, 0z, etc, whenever you say the new "insert model here". Someone invevitably is going to say "did they change it upgrade it, etc. and sometimes there are paralel models running so new nam may actually mean a new model. Thanks.

It's been showing 4-5" pretty consistently which is why I was asking. The GFS is similar in totals then. The NAM is a bit higher. Those numbers coming from an SREF mean scare me a bit, being as its a low res ensemble and the fact that the model scores well with regards to verification. I think most areas probably see 4-6" with isolated higher totals. Some areas in NJ have already seen over 3.0" according to dopplar radar estimates.

New convection forming over Burlington County moving very slowly north. Should impact most of NJ during the evening rush hour or shortly after.
